1 Claim. 1

This invention relates to fasteners for window panes or the like and hasfor an object to provide a strip fastener which is easy to handle andapply and which effects a tight permanent seal. The strip is primarilyusable to replace putty for securing window panes in sash.

Various other objects and advantages will be apparent as the nature ofthe invention is more fully disclosed.

Although the novel features which are characteristic of this inventionare pointed out in the claim, the nature of the invention will be betterunderstood by referring to the following description, taken inconnection with the accompanying drawing in which a specific embodimentthereof has been shown for purposes of illustration.

In the drawing:

Fig. 1 is a front elevation of a window sash and pane embodying thepresent invention;

Fig. 2 is a transverse section on an enlarged scale taken on the line2--2 of Fig. 1;

Fig. 3 is a section taken on the line 33 of Fig. 2;

Fig. 4 is a detail view of a fastening and sealing strip embodying thepresent invention; and

Fig. 5 is a detail view of the blank used in making the fastening andsealing strip.

In the various figures like parts are identified by like referencecharacters.

Referring to the drawing more in detail, the invention is shown asapplied to a window comprising a sash ID in the form of a rectanglehaving top and bottom members II and I2 respectively and side members[3. The sash I0 is shown as mounted in a fixed frame I4 the details ofwhich form no part of the present invention.

The sash I0 is shown in Fig. 2 as having a flat surface [8 defining anopening to receive a pane and having on the inside a flange 2| which maybe milled in one piece with the sash or may constitute a separate piecesecured to the sash as in the usual practice.

The pane 20 is seated against the flange 2| and secured by a fasteningand sealing strip embodying the present invention. The strip '25comprises a strip 26 of flexible sealing material such as rubber,natural or synthetic, which is waterproof, is resistant to theatmosphere, and which is capable of retaining its flexible sealingcharacteristics.

The sealing strip 26 is secured in a metal strip 21 which is bent into aU-shaped cross-section having inner and outer legs 28 and 29respectively between which the sealing strip is clamped. The inner leg28 is made shorter than the outer leg 29 so as to provide clearance forthe pane 20. The sealing strip 26 extends beyond the end of the outerleg 29 a sufiicient distance to provide flexibility for conforming tothe window pane 20. The metal strip 21 is made of a material which isresistant to atmospheric conditions, for example aluminum or stainlesssteel. For securing the same to the sash points 30 are struck out of theblank as indicated in Fig. 5 and are bent to extend about normal to thestrip so as to be driven into the flat surface 18 of the sash I0 at aninclined angle, thereby firmly securing the strips 25 in place andpreventing the row of points from splitting the edge of the sash.

In use, the pane 20 is placed against flange 2|, the strip 25 is cut tothe proper lengths to fit each side of the pane, preferably with theends 3| bevelled for a tight fit (Fig. 1). The strip is then pressedfirmly against the pane and sash to cause the protruding portion of thesealing strip 26 to conform to the pane and the points 30 are driveninto the sash with a hammer. The points thus serve to hold the strip 25permanently in place. The strip may be painted if desired. The metalstrip 21 is made from stock sufiiciently thick to provide rigid partsfor securing and holding the strip in place.

If it becomes necessary to remove the pane 20, the strip 25 can beeasily removed by inserting a tool and prying the same from the sash.Hence the strip is well adapted for use by home owners as no specialskill is required in applying or removing the same. In addition muchless time is required than in the case of putty or the like.

Although a specific embodiment has been shown and described for purposesof illustration it is to be understood that the invention may be appliedto other uses and that changes and adaptations may be made therein aswill be apparent to a person skilled in the art.

What is claimed is:

In a window having a sash and a pane, a sealing and fastening strip forsecuring said pane in said sash, comprising a strip of flexible sealingmaterial and a metal fastening strip bent into a U-shaped cross-sectionto form inner and outer legs between which said flexible strip isclamped with the flexible strip extending beyond the end of said outerleg, said metal strip having fastening points struck out of the metalthereof at the base of said inner leg and projecting inwardly therefromsubstantially normal to said inner leg to be driven into said sash at anangle to draw said strip into securing engagement with said pane, saidouter leg being longer than said inner leg by an amount such that thefree edges of said legs are about equally spaced from said pane whensaid strip is in sealing position.
